Description
Technical Field
The invention relates to the technical field of composite material machining, in particular to a flexible quick-adjustment self-centering suction tool suitable for a part containing energy rotation and a centering method.
Background
Because some energy-containing revolving body parts processed by full-profile surfaces have higher requirements on clamping reliability and centering precision, the composite materials belong to weak rigid materials and are easy to deform, and a plurality of conventional metal clamping methods (such as clamping of a chuck, adhesion positioning and the like, which can damage or stain a workpiece) are difficult to popularize and apply in the field. However, the vacuum adsorption technology is very effective for reliable and centering clamping in the processing of the energy-containing parts, and has obvious advantages in the aspects of preventing product clamping damage, one-time full-profile processing and the like. The vacuum chuck ensures the isostatic stress of the suction end surface by using the Pascal principle, and is widely used for clamping weak-rigidity or precision parts, such as various composite materials and optical glass devices. Although traditional cavity formula vacuum chuck obtains more general use, still have some problems, can arouse the work piece center to cave in and cause great deformation after adsorbing, the cutting fluid easily gets into the vacuum cavity and reduces the absorption reliability through adsorbing the contact surface, and sucking disc structural fixation can not be from the centering, lack the flexibility and be difficult to satisfy many varieties part quick replacement requirements. These problems all have a certain influence on the processing precision, production efficiency and clamping safety of the energy-containing component.
At present, the special application of energetic material machining and dress card is limited, and few general vacuum suction tool development to this field, borrow the frock design experience of the same kind for reference, many manufacturers' customization development have non-standard product, through installing soft rubber pad additional between many empty ceramic sucking discs and processing silicon chip like Applied Materials company to adopt the aperture that runs through of evenly distributed, can reduce work piece deformation and improve machining efficiency. Une of Japan proposes a cylinder pin type vacuum chuck, which does not use porous ceramics but uses cylinder pins densely and uniformly distributed on the surface thereof, and the composite material workpiece to be processed is in contact with only the short cylinder end face, so that the processing surface thereof can be made extremely flat, and the adsorption effect of minute dust can be eliminated. Bendfeldt increases the suction area and significantly increases the suction force of the workpiece through the expansion of the groove suction cup design. Strasbaugh corporation has developed a zoned vacuum chuck that can select a vacuum suction area based on the machining of sheet parts of different sizes, i.e., can only internally evacuate when machining small diameters, and can both internally and externally evacuate when machining large sheet parts. The vacuum chuck is mainly used for grinding the end face of a sheet part, and the size of the vacuum chuck and the size of a machined part need to be matched for use under the condition of needing end face and excircle turning. Especially for the flexible production line of small-batch and variable-size part processing, the vacuum chucks with various sizes and specifications need to be frequently installed and replaced, repeated installation and positioning calibration are needed each time, the production preparation time is long, the processing efficiency and the production flexibility are greatly influenced, and the flexibility is reduced.
In summary, there still exists a certain popularization difficulty for the application process of the vacuum chucking technology in the machining of the energy-containing revolving body, and the reason is as follows: 1) the processing and clamping safety of the energy-containing rotary parts have special requirements on the material selection and the process structure design of the vacuum suction tool; 2) the vacuum suction has the functional requirements of sealing performance and automatic alignment during the full profile processing of energy-containing components; 3) the cavity type vacuum suction tool commonly used at present has single functional structure and lacks flexibility. Therefore, in view of the current technical situation of vacuum chucking of energetic materials, the structure of a vacuum sucker needs to be improved, the quick and agile processing adaptability of the sucker is enhanced, and a vacuum sucker with uniform distribution stress, adjustable vacuum area and convenient self-centering is designed and developed so as to adapt to the high-efficiency and safe processing requirements of energetic material parts, which is very beneficial to solving the practical problems in production.
